Supplementary file1 (MP4 18781 KB) The patient shows conjugate torsional pendular nystagmus with a small vertical component in the left eye in the primary position along with symmetrical palatal tremor. During lateral gazes, gaze-evoked and downbeat nystagmus are superimposed on the torsional pendular nystagmus
